Tell us about yourself!
great ible. One thing to keep in mind, every piece has a dead spot. Ie, a point of non vibration, which is the best place to drill the hole to connect it to the 'rail'. Sprinkle some fine salt on each piece when you test for tuning....you'll see that point appear an inch or so from either end, where the salt settles (Cool experiment to share with kids) you can test this point by pinching piece at 'dead point' and tap, then pinch elsewhere and notice how much vibration is smothered. Hope this makes sense.
